The document discusses conventions of horror film trailers, including how lighting is often dark and eerie to create an unsettling atmosphere for viewers. Settings are typically isolated locations that increase tension. Common colors used are red, black and white which symbolize blood, darkness, and ghosts. The editing starts with long shots and slow cuts but speeds up during scary moments. Music gets faster and more intense during climactic parts of the trailer. On-screen text and a final "sting" at the end are meant to match the film's atmosphere.
